这篇专题文章回顾了碳纳米管和石墨烯定制组装成三维结构的最新进展，特别强调了我们自己采用自组装原理的研究。碳纳米管和石墨烯可以通过溶剂分散的定向组装组装成大孔膜、空心球形胶囊或空心纳米管。这种方法具有成本效益，有利于大规模组装，但预先要求在溶剂介质中稳定分散。纳米催化剂阵列的定向生长是另一种很有前途的方法，它可以控制石墨材料的形态和性质以及它们的组装。此外，上述两种方法可以协同集成，产生由生长在柔性石墨烯薄膜上的垂直碳纳米管组成的碳混合组件。基于可扩展自组装原理的定制组装为大规模生产提供了可行的途径，可扩展到石墨碳材料在纳米电子、显示器、传感器、能量存储/转换设备等领域的最终利用，包括未来的柔性设备。
This Feature Article reviews recent progress in the tailored assembly of carbon nanotubes and graphene into three-dimensional architectures with particular emphasis on our own research employing self-assembly principles. Carbon nanotubes and graphene can be assembled into macroporous films, hollow spherical capsules, or hollow nanotubes, via directed assembly from solvent dispersion. This approach is cost-effective and beneficial for large-scale assembly, but pre-requests stable dispersion in a solvent medium. Directed growth from a nanopatterned catalyst array is another promising approach, which enables the control of morphology and properties of graphitic materials as well as their assembly. In addition, the aforementioned two approaches can be synergistically integrated to generate a carbon hybrid assembly consisting of vertical carbon nanotubes grown on flexible graphene films. Tailored assembly relying on scalable self-assembly principles offer viable routes that are scalable for mass production towards the ultimate utilization of graphitic carbon materials in nanoelectronics, displays, sensors, energy storage/conversion devices, and so on, including future flexible devices.
